Meteorology

moisture inversion

Weather; Meteorology

An increase with height of the moisture content of air; specifically, the layer through which this increase occurs, or the altitude at which the increase begins. See inversion.

moisture equivalent

Weather; Meteorology

The weight percentage of water (with respect to dry weight) retained by an initially saturated 1-cm-thick soil sample after it has been subjected to a centrifugal force 1000 times the force of ...

moisture pooling

Weather; Meteorology

The development of an area in the boundary layer (e.g., often observed on surface or 850-mb charts) where moisture values become higher than in the surrounding region. Moisture pooling typically ...

The adjustment of observed precipitation in a storm by the ratio of the estimated probable maximum precipitable water over the basin under study to the actual precipitable water calculated for the ...

saturation adiabat

Weather; Meteorology

On a thermodynamic diagram, an isopleth of equivalent potential temperature or pseudoequivalent potential temperature. Moist adiabats on most diagrams are drawn for the pseudoadiabatic process, in ...

moisture

Weather; Meteorology

In meteorology, a general term usually referring to the water vapor content of the atmosphere, or to the total water substance (gaseous, liquid, and solid) present in a given volume of air. In ...

saturation-adiabatic process

Weather; Meteorology

An adiabatic process for which the air is saturated and may contain liquid water. A distinction is made between the reversible process, in which total water is conserved, and the pseudoadiabatic or ...
